Hello, I studied your diagnosis - the main problem: Event 1 of 100: Event ID 16# 4548 STOP due to I/O management Read the topics and FAQs below: Advice on fault: STOP due to I/O management CPU stop due to Event ID 4548/494D Have CPU stop due to Event ID 4548/494D Why does my SIMATIC S7-300 CPU go into STOP with error 16#4548 "Stop by I/O administration"? *********************** So: 1. Check that the organizational blocks for diagnosing hardware problems are loaded in the PLC and you have in your project - for example, the OB86 block (and its brothers ...) 2. Check if the PLC, periphery is correctly connected to power supply - L+ and M- 3. Check the voltage of the PLC power supply - The voltage should be in the range of 22-26 volts (ideally ...) 4. Check the PLC voltage ripple (if all of the above did not help) - you may need to put voltage interference protection or something similar |
